ABSTRACT:
An ice-making machine comprises an evaporator structure submerged in suitable ice-forming liquid in a holding tank. The evaporator structure comprises a cylindrical single-tube evaporator disposed vertically on a support frame on the base of the tank and connected to refrigeration plant externally of the tank. A rotary scraper assembly having a scraper blade for scraping ice continuously off the outer cylindrical surface of the evaporator is mounted in the tank, so that the ice floats to the top of the liquid for pumped removal from the tank if required. The scraper assembly is rotated by a motor mounted above the tank. The evaporator and scraper structure form a unit which can be used in different liquid holding tanks.
